First is to make equations for both sides.
Let x be the number of the miles.
a be the charge of the first company
b be the charge of the second
a=$35+$0.25(x), b=$40+$0.20(x) .
then a=b
Substitute the equations
$35+$0.25(x)=$40+$0.20(x)
$0.25x - $0.20x = $40 - $35
$0.05x = $5
x= $5/$0.05 , cancel out the unit.
x= 100
To justify substitute x to both the equations a and b.
a= 35 + 0.25(x)
a= 35 + 0.25(100)
a= 35 + 25
a= $60
b= 40 + 0.20(x)
b= 40 + 0.20(100)
b= 40 + 20
b= 60
a=b
60=60.

Just subscribed wish you the best on your channel!!!
Volume of room = 500 * 300 * 200 cm
= 30000000 cm³
Volume of 1 box = 10 * 6 * 4
= 240 cm³
Thus, number of boxes in the room
= 30000000/ 240
= 125000 boxes ;
Thus, 125000 boxes can be stored in the room.
The gene flow would increment or quality stream would increment between the two parts, and speciation would not happen. The probability of speciation would diminish as qualities were shared between the two gatherings. Kept up quality stream between two populaces can likewise prompt a mix of the two quality pools, diminishing the hereditary variety between the two gatherings.
Answer:
I prefer to express solutions to inequalities using interval notation. Both formats are are important but I think interval notation is easier to understand and represents better the solutions.
For example, if you have the following inequation:
x-2> 1
x>3
Therefore, the solution could be written either x>3 OR (3, +inf). But what happens if the solution to the system of equation is x>3 or x<-3? The solution can be easily written as: (-inf, -3) U (3, inf) instead of 'x>3 or x<-3' which can be confusing.
